If you're worried about the state of the economy, don't blame the pornography industry for not trying hard enough. In 2005, DVD and video sales alone raked in $1 billion for the adult entertainment industry in the U.S. [source: Safe Families]. That's not counting online revenues, where money and page views flow toward XXX Web sites, which make up more than 10 percent of all sites. And many who stay in hotel rooms take advantage of the access and perceived anonymity such a stay provides: One study by a hotel association found that 55 percent of all hotel guests watch pornographic content on the hotel TV [source: Safe Families].

It's perfectly normal for adults to look at pornography, and many happy couples make a practice (or experiment) of watching it together. If you discover -- or have kept silent about -- your partner's propensity for porn, rest assured that it's probably not a big deal. There are exceptions, of course. Illegal, underage or excessively graphic or violent pornography are clearly major issues.

You should be concerned about addiction if your partner spends so much time looking at pornography that it disrupts normal life, such as work and personal relationships. If pornography has replaced sex in your relationship, you and your partner may want to speak with a marriage counselor or sex therapist about it.
